• We are seeing a view of the future where low carbon fuels can be substituted for petro-based fuels without sacrificing performance in the plane or through the infrastructure.

• With any supply chain system that is made up of multi stakeholders you need to have alignment from being to end

• Renewable jet fuel was supplied at Chicago O’Hare using the existing airport hydrant fueling infrastructure, supplied via pipeline off airport, and tankage on/off airport.

Supply Chain Dynamics – The New Normal

• Strategy: Leverage installed assets at Luverne and adding the capability to produce 7-10 MGPY of hydrocarbons.

• Luverne is a proving ground for products and supply chain development.

• Completed FEL2 (Front-end loading) engineering for construction which includes robust planning and design.

• Working on finalizing off take agreements and securing financing
